EVerest is an EV charging software stack. Prior to version 2025.10.0, during the deserialization of a DC_ChargeLoopRes message that includes Receipt as well as TaxCosts, the vector <DetailedTax>tax_costs in the target Receipt structure is accessed out of bounds. This occurs in the method template <> void convert(const struct iso20_dc_DetailedTaxType& in, datatypes::DetailedTax& out) which leads to a null pointer dereference and causes the module to terminate. The EVerest processes and all its modules shut down, affecting all EVSE. Version 2025.10.0 fixes the issue.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
